[PATCH net-next v3 00/13] virtio: support packed ring
Hi,
This patch set implements packed ring support in virtio driver.
A performance test between pktgen (pktgen_sample03_burst_single_flow.sh)
and DPDK vhost (testpmd/rxonly/vhost-PMD) has been done, I saw
~30% performance gain in packed ring in this case.
To make this patch set work with below patch set for vhost,
some hacks are needed to set the _F_NEXT flag in indirect
